Status Code Exception (com.google.gwt.user.client.

I'm getting this error while running the login application (Using GWT-RPC). How can I resolve this? I have provided the error list as well. What I'm missing?

You registered your servlet for the URL "/Login", but you're calling "/login".

You need to change either the <url-pattern> to lower case, or your @RemoteServiceRelativePath to upper case. Then restart the server.
